Autodesk

Autodesk, Inc., is a 3D design, engineering and entertainment software company. Customers across the manufacturing, architecture, building, construction and media and entertainment industries use Autodesk software to design, visualise and simulate their ideas.

As of 1st of August 2016, design and creation suites are no longer available for purchase.
You can continue to receive support and use the software and benefits for as long as you continue to renew your design and creation suite subscription or maintenance plan.
Beginning in October, Autodesk will offer a convenient way to switch from a design and creation suite subscription to an industry collection, which offers more tools at a comparable price.
